To provide a composite material pipe which will not obstruct visual field and makes a small temperature change.

This composite material pipe is characterized in that a heat control layer adhering to the outer surface of a composite pipe having an organic material ? matrix and a carbon fiber reinforcing material is a composite material having an organic material matrix and an organic fiber reinforcing material and reducing sunlight absorptivity. The heat control layer may be formed by using glass fiber reinforced material, a material containing a white pigment making the sunlight absorptivity of the outer surface 0.7 or less, or a metal coating film having an elliptical section gently held by a stopper ring or an elastic support device.
